Mary and Lee Humphrey have been dining at a McDonald's for 17 years

Lee and I first ate in the Eastbourne McDonald's in 1990 and we've been back every weekday ever since. We had just moved over from Vancouver and we just fell in love with McDonald's.

We call it "the office" now and our relatives will ask us how the office is and have a little joke about it. We almost have our own table and if someone else is sitting there then, oh boy, I have to sit somewhere else and I feel like I'm lost. We never go to any other restaurants, you'll never see us anywhere else.

What do we love about it? McDonald's has always been very pleasant, and the people who work and go there are always very polite and friendly. In all these years, we have never, never had a cross word from anybody. We have people coming to sit with us who are a quarter of our age, and I love listening to the young kids and the students. And if they haven't got time to talk to us, then they'll just wave and go about their business.

We both order a double hamburger with one portion of chips between us, Lee has a cup of coffee and I give him one of my hamburgers, so I have one and he has three. I did once try the Big Deli sandwich and, I tell you, I couldn't walk out of the door it was that big!

We don't eat big when we come home, we like to sit down in the afternoon and watch Deal or No Deal with a Magnum chocolate-covered ice cream. We sit there licking it like two little old kids.

I've heard it said that people who go to McDonald's all put on weight - don't you believe it! I'm very slim and so is Lee. It's just nonsense about McDonald's not being healthy. Lee will have a bowl of cereal in the morning, and I'll make him a pre-cooked roast beef at the weekends, but there's 400 calories in our ice cream so we don't eat much else.

We were there all through that terrible time of the BSE crisis when they said don't eat beef. We were just fine and we're still healthy now. We're both 84 and there's nothing wrong with either of us. They're always going to criticise McDonald's and I don't understand why - it is one of the cleanest places you'll ever go to and we just love it.

Stephen Best and his wife Helen have been eating at the French in Manchester for 15 years

I first went to the French in 1992, I had moved up from London and, for me, it was just this sudden pleasure of finding somewhere in Manchester that was similar to the Savoy or Claridge's, with first-class service and fine food. I now go with my wife three times a week on average, which is definitely a lot, but I don't think it's obsessive or anything. One of the reasons we go so much is because all my wife will make for dinner is reservations and she is quite set in her ways with food; she doesn't like to go for an Indian or a Chinese, so we're restricted in where we go together.

It's never become a chore, as the French has a table d'hote menu that varies every two weeks or so, and if I want something in particular, then all I've got to do is pick up the phone. They'll cook things especially for me, which is one of the advantages of being a regular customer. There are other perks too, such as being greeted by friendly faces and having your little foibles catered for.

The French has changed over the years. It's moved with the times and has had various chefs, from the Michelin-starred to younger guys with talent. Trends might change over the years, but they always have old favourites like chateaubriand or dover sole on the menu. At one time you used to see a steak diane or crepes suzettes flambéd at the table but that's very rare now. I do miss the old-fashioned fish trolley they used to have all packed up in ice, but apparently health and safety doesn't allow for that now.

When we eat at the French, we have a driver who regularly picks us up, and we always have a bottle of Louis Roederer champagne while we ponder the menu and the wine list. Then we go in to dine. We always sit at table seven because it gives my wife a good view of who is coming in and out. The other night a particular Swedish football manager was at the next table. Over the years I've spent fortunes there and, with the benefit of hindsight, it has absolutely been worth it. I don't smoke, I don't gamble, so eating at the French is one of my pleasures in life. Other people might spend fortunes on holidays, but because of a medical condition I can't fly so going to the French is a way of getting some great world cuisine without leaving the city.

Tim Wilson has dined at the Kashmir in Bradford for 30 years

There's a little plaque on the wall of the Kashmir that says it was established in 1957, which I always remember because that was the year I was born. I first went to the restaurant when I was 20 and I've been going back twice a week now for the past 30 years. Although there is a ground-floor section, I go downstairs to the bit everyone calls the cellar. It hasn't changed a great deal over the years I've been going. It went through a refurb about five years ago, but before then it had the same character as it did when I first started going - the same old formica tables and plastic chairs. I was on holiday when they had the refurb, so it was nicely timed.

I usually have the same thing every time I go - the chicken tikka masala with chapatis. I normally have a starter as well, either the fish pakora or the shami kebab. I have tried other things on the menu like the chicken tikka off the bone with chips, but I keep going back to chicken tikka masala. If you work it out, over the past 30 years, I've probably had 3,000 chicken tikka masalas and I reckon I've spent more than £10,000 at the Kashmir. They should do one of those loyalty cards.

I don't cook at home all that often; I'm single and it's hardly worth cooking for one, so I tend to eat out a lot. Obviously, we've got a lot of Asian restaurants in Bradford but I prefer the Kashmir because the food is always freshly cooked. I think the food is a bit addictive. I get withdrawal symptoms if I don't go.

I think the key if you want customer loyalty is to make the food good quality and to deliver it consistently, so you always know what you're going to get. I suppose in one respect it is maybe a bit boring to keep going back to the same place. Sometimes I do go to different restaurants to break up the monotony, but I always end up back at the Kashmir and I'll keep going back as long as it's there.
